Background

Since the origins of the first bipeds, about 7 million years ago, it is possible to observe some evolutionary trends in our lineage. Erect posture and bipedalism favored the development of the brain over a powerful body structure, promoted important changes in the mechanisms of reproduction, birth, food intake and absorption, as well as the control of body fluid homeostasis and temperature. Our species, Homo sapiens, underwent intense environmental selective pressures by migratory movements, and around 10,000 years, the invention of agropastoral production methods started the process of transition from a way of life based on foraging to another form of sociocultural organization, ultimately resulting in big cities that we know today. Since ancient times, large human settlements influenced the evolution (adaptive and non-adaptive) of many species, including ours. Cities can alter gene flow, promote genetic drift, increase mutation rates, affect access to food and water, affect environmental temperature, as well as contribute to environment deterioration (pollution), composing a perfect scenario for the development of epidemics. In this volume, we will explore how new environments (including large urban areas) have favored in a very short time scale new evolutionary pressures, resulting in a greater susceptibility to certain diseases in human populations. We are interested in amassing a volume covering a great range of research topics, including (but not limited to) the impacts of urban settlements, post-agricultural diets, as well as changes in the levels of physical activity and energy expenditure on the patterns of disease in human populations. Cardio-respiratory diseases like atherosclerosis, hypertension, ischemic cardiac injury may be the consequences of evolutionary mismatch due to the rapid changes of working, feeding, and living conditions that occurred in the last decades. Likewise, rapid environmental transformations related to urbanization, climate change, technological advances (e.g. assisted reproductive techniques), food shortages, social and economic factors (e.g poverty, migration), air, water and soil pollution (e.g endocrine disruptors), occupational hazards, among other aspects can pose challenges or be allies in the reproductive process of humans. The topic on contemporary society and human reproduction can also be addressed focusing on the history of contraception, as well as on the different aspects of demographics in relation to the role of grandparents and post-reproductive evolution and physiology. The impacts of modern lifestyle on human health can also be studied from a cellular and physiological level, including antenatal events like fetal programming. We aim to cover and to integrate new findings on the impact of recent changes in the way of life of human populations since the adoption of agriculture and the intensification of agropastoral methods, including how aspects related to demographic aspects, settlement patterns, diet composition, and physical activity levels might have influenced the patterns of disease in the last 10,000 years. All types of articles (Original Research articles, Methods, Comprehensive Reviews, Mini-reviews, etc.) are welcome.

Frequently asked questions

  • Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

    Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

  • The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

    Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

  • As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

    A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

  • Each Research Topic must be approved by the specialty chief editor, and it falls under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

    In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

  • Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

    As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

    Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

  • Frontiers offers multiple article types, but it will depend on the field and section journals in which the Research Topic will be featured. The available article types for a Research Topic will appear in the drop-down menu during the submission process.

  • A team of guest editors (called topic editors) lead their Research Topic. This editorial team oversees the entire process, from the initial topic proposal to calls for participation, the peer review, and final publications.

    The team may also include topic coordinators, who help the topic editors send calls for participation, liaise with topic editors on abstracts, and support contributing authors. In some cases, they can also be assigned as reviewers.

  • As a topic editor (TE), you will take the lead on all editorial decisions for the Research Topic, starting with defining its scope. This allows you to curate research around a topic that interests you, bring together different perspectives from leading researchers across different fields and shape the future of your field. 

    You will choose your team of co-editors, curate a list of potential authors, send calls for participation and oversee the peer review process, accepting or recommending rejection for each manuscript submitted.

  • As a topic editor, you're supported at every stage by our in-house team. You will be assigned a single point of contact to help you on both editorial and technical matters. Your topic is managed through our user-friendly online platform, and the peer review process is supported by our industry-first AI review assistant (AIRA).

  • If you’re an early-stage researcher, we will offer you the opportunity to coordinate your topic, with the support of a senior researcher as the topic editor. This provides you with valuable editorial experience, improving your ability to critically evaluate research articles and enhancing your understanding of the quality standards and requirements for scientific publishing, as well as the opportunity to discover new research in your field, and expand your professional network.

  • Yes, certificates can be issued on request. We are happy to provide a certificate for your contribution to editing a successful Research Topic.
